Isn't the idea to get rid of the hook by quick release? The ball and socket eliminates the hook. The problem with anything quick release is that it works at the most inopportune times.Like double trapped going to A in the lead(could happen).

There is always another boat nearby during a race. Everyone should be prepared.

Having the hose on the chase boats is also an interesting idea.
